Just to add some more fuel to the fire: has anybody been using EXR to  
store stereo data?
If so how? "left" and "right" layers? etc, etc.

My inclination is to write them as:

	left.[RGBAZ]
	right.[RGBAZ]

and if there are additional layers (e.g.):

	left.diffuse.[RGB]
	right.diffuse.[RGB]

But it seems like nailing down "left" and "right" (and/or "center")  
would be a good idea
along with any accompanying attributes (matrices).
